| Abstract |
At the main workplaces in a sorting and sheet-rolling works, noise was measured and hearing sensitivity was investigated in 229 men aged 36.1±9.8 years (mean length of service 9.7 years), taking into consideration the excessive equivalent levels and its impulsive nature. Hearing thresholds for 4 and 6kHz and average speaking frequency were elevated, and the proportion of subjects with hearing thresholds above 30dB for all frequencies tested was larger among roll operators, furnace workers, cutters, crane operators, markers, packers, quality control staff and dispatchers than among subjects working at lower noise levels or exposed for shorter times to intense noise. Change in hearing sensitivity was more closely related to age than to duration of occupational experience. Summary in English. |
